Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 3,655,355, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 3,655,355 | |
| -1 | -3,655,355 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,655,355.
Example:
1 x 3,655,355 = 3,655,355
and
-1 x -3,655,355 = 3,655,355
Notice both answers equal 3,655,355
With that explanation out of the way, let's continue. Next, we take the number 3,655,355 and divide it by 2:
3,655,355 ÷ 2 = 1,827,677.5
If the quotient is a whole number, then 2 and 1,827,677.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 3,655,355 | |
| -1 | -3,655,355 |
Now, we try dividing 3,655,355 by 3:
3,655,355 ÷ 3 = 1,218,451.6667
If the quotient is a whole number, then 3 and 1,218,451.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 3,655,355 | |
| -1 | -3,655,355 |
Let's try dividing by 4:
3,655,355 ÷ 4 = 913,838.75
If the quotient is a whole number, then 4 and 913,838.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 3,655,355 | |
| -1 | 3,655,355 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 1,621 | 2,255 | 8,105 | 17,831 | 66,461 | 89,155 | 332,305 | 731,071 | 3,655,355 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -1,621 | -2,255 | -8,105 | -17,831 | -66,461 | -89,155 | -332,305 | -731,071 | -3,655,355 |
